COMPOSITE RAILWAY-TIE.

Specification of Letters Patent. Patented Sept; 28 1915.

' Application filed May 25, 1915. Serial No. 30,376.

To all whom it mag concern Be it known that I, WILLIAM H. KNIcK- nnrur, a citizen of the United States residing at Somonauk, in the county of bekalb and State of Illinois, have invented certain new and useful Improvements in Composite Railway-Ties; and' I do declare the following to be a full, clear, and exact description of the invention, suclr as'will enable others skilled in the art t Jvhich it appertains to make and use the same.

- This invention relates to-the subject of track structures for railways, and has spe-' cial reference to cross ties which are com- 'monly termed reinforced cement-or composition. ties-and'which are employed as a substitutsi for the ordinary wooden ties generally use Tothis end the invention contemplates a simple and thoroughly practical construction of tiewhich may be characterized as a composite tie inasmuch as it embodies in its organization the general characteristics and advantages of 'a cement or concrete tie as well as those of a metallic tie, while also the advantages of a wooden tie by'provid ng wooden cushions for the bearing supports of the rails.

A general object of the invention is to provide a composite tie possessing 1n the invention consists of certain novel features of construction, and the combinationjand arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings, Figure 1 represents a longitudinal section of 'a-com- ,plete tie constructed invaccordance with this invention; Fig. 2 isa plan view of the metallic frame detached; Fig. 3 is a side elevation thereof; Fig. 4 is a transverse vertical section taken on the line 4-4 of Fig. 3; Fig. 5 is anenlarged detail longitudinal section taken on the line 5-4-5 of Fig. 2.

The improved tie contemplated by the present invention consists of a concretebody portion 1 in "which is embedded and completely envelopeda longitudinally extending metallic reinforcing I structure WlllCll constitutes a metal frame for the tie body While at theasame time acting in the.

c acity of a reinforcing unit to strengthen and stiffen the tie throughout. The term concrete is used-in" its general and broad application and cemprehends any of the cements or cement compositions such as are ordinarily used in structural work of difierent kinds. Thus it will be understood that the present invention is not limited to any particular kind'of concrete or cement material in the formationof the body portion 1 of the tie. In this connection it'will also be understood that the term concrete body ,75 I

portion is simply intended to include the concrete envelop or filling material for the 'tie proper which essentially consists of the metallic bars 2 and 3 and the cushions 4 and 5 associated therewith in the manner hereinafter more fully described.

The concrete body-portion 1 of thetie is intended to preserve the conventional ou tline and dimension of the ordinary wooden cross tieand is designed to bemolded and compressed about the interior metal frame by any suitable or improved means to provlde a tie of sufficient width-and having the necessary bearing surfaces to properly hold it in the ballast and to meet the traffic requirements. p

The distinctive feature of the invention resides inthe form and construction of the interior metallic frame which as shown comprises two angle bars 2 and 3 spaced laterally apart and secured'in spaced relation by means of pairs of longitudinally spaced cross bars (land '7 arranged near the opposite ends of the bars 2 and 3. Each pair of these cross bars is constructed of two angle irons 8 and 9 with the opposite ends of their vertical flanges cut away to leave an upright flange which is of a length corresponding to the distance which it is desired to? space the 1 bars 2 and 3. The projecting ends 11. and

12 of the lateral members or flanges of these cross bars pass under and engage the-lower faces of the lateral flanges of the bars 2 and 3 and are secured thereto. bysuitable fastening elements 13. Secured to the upright 1 flanges 10 of the cross bars Sand 9 are two plates 1ft and 15 which extend beyond the 30 a a iaggainstlongitudinal movementby the bars"v Qan-d 3 and against lateral movement by the platesl k-and which are secured to theupperjand lower edges of the bar'si 2 and 3 4 and are'providedat their upper endswith inturned flanges lf6fand at theinlowr ends hyvith vinturned flanges 1"7', "th"e flanges I7 5 being preferably of greater; Width than the fiangeslQi-to 'afi'orda proper {supportingbase l I Q 710, the' bearing surface and strength necessary vin"orderj that the upper faces of theblocks may be exposed as much as possible to re.-

' "ceive and support the track'rails which they v 'aiede'signed to" carry. These rail cushion l5 to't -he'ditancebetweenfthebars 2' and3 and 'arefofial ength suiiicient to afliord ample sup-f porting surface for the track rails which are" ui'ng blocks 'are of a width corresponding as? bemounted thereon. These blocks*20 have their-upper faces recessed at their opposite ends as shown at 21 to receivethe 5 flanges 16"ofi the supporting plates 14 andl-5 l'i'iof the plates 1i and 15 between whichan'dthe upper flanges "16' thereof said blocks *areise'curely clamped to hold them against vertical movement, the block's being held cross bars 8 and 9 whichconnect said bars "arid-3". Referring to the mounting-of these I in the tie'b'ody where rai'l' bearing 'supports'are to beprovided' for the opposite, rails and when the cement. body 1 is formedtherearound', the upper faces of these blocksare left exposed and are: arranged flnshfwith, the upperiaces of the cement suitable fastening elements;. H

' From the above descriptiomit willbe ob vlousthat when the metallic frame just des'ci i'b'ed is incased in thec'ementibody 1, the

Y cement will flow around the lateral flanges hi0 ofthe bars 2 and 3 and the Crossbars Spand v 9" and thus securely lock said'frarne in said body againstall possibility of its movement in any direction therein. Y
